SUMMARY In microsporocytes of Stangeria, Impatiens and Tradescantia and in sporocytes of Equisetum all plastids and mitochondria aggregate for a short period at one side of the early prophase I nucleus. Later the organelles disaggregate and during metaphase I and anaphase I they organelles migrate towards the equator of the cell. In Impatiens, Clarkia, Lysimachia and Equisetum all these organelles aggregate in the equatorial plane, thus dividing a dyad into two parts. After meiosis II the equatorial aggregation of organelles is reshaped and divides a tetrad into four parts. Inside the aggregation of organelles, cell plates are simultaneously set up.
